Michael Humphrey - CEO
Michael Humphrey is the CEO of Austin-based and privately held Human Performance Labs, makers of PureSport, a collection of new, patent-pending performance drinks—made by adding water—that feature the optimal carbohydrate-to-protein ratio of 2:67-to-1, endorsed by Champion swimmer Michael Phelps and Champion gymnast Nastia Liukin.
Humphrey, whose expertise is in revenue generation, raising private equity, venture capital, and managing companies for institutional investors, joined Human Performance Labs in October 2007. From 2001 to 2007, Humphrey served as Executive Vice President for Compass Learning, an Austin-based educational software company that was acquired in March 2007 by Ripplewood Investments/Reader’s Digest. Under Humphrey’s leadership, the company forged key strategic partnerships with organizations including Dell Computer and the Northwest Evaluation Association and company revenues went from $20 million to more than $50 million in six years.
Before joining Compass Learning, Humphrey served in Business Development at Broadcast.com where he closed major transactions with companies including Pearson Publishing, McDonalds Corporation and Pepsi Corporation. Humphrey continued in a Business Development Role after Broadcast.com was acquired by Yahoo!
From 1990 to 1997, Humphrey served as Vice President of Sales for Simon & Schuster’s Children’s Educational Publishing Unit, growing their sales revenue from $30 million to more than $300 million.
In addition, Humphrey served as part of the creative team that managed the roll-out of VH-1’s Save the Music Program with Blockbuster Video, and, from 1981-1984, worked on the Olympic Development Team at ABC Sports.

Dr. John Ivy
PureSport™ Workout and Recovery nutritional performance sports drinks with protein were developed by Dr. John Ivy, Chairman of Kinesiology and Health Education, Teresa Lozano Long Endowed Chair at The University of Texas at Austin.
Dr. John Ivy was trained and has experience in human performance research and testing. His research focuses on the acute and chronic effects of exercise on muscle metabolism, with special emphasis on carbohydrate regulation.
Currently, Dr. Ivy is investigating the locus and cause of muscle insulin resistance, as well as the mechanism(s) by which muscle insulin resistance is reduced with exercise training and nutritional supplementation.
Dr. Ivy is also investigating the regulation of muscle glycogen synthesis, means of enhancing the rate of muscle glycogen synthesis, and the effects of various ergogenic aids on physical performance.
Dr. Ivy has been a University of Texas faculty member for 25 years. He is a fellow and former Ambassador for the American College of Sports Medicine, a Fellow in the American Academy of Kinesiology, and a member of the American Physiological Society, and American Diabetes Association.
Dr. Ivy has served or is currently serving on numerous editorial boards including the American Journal of Physiology, International Journal of Sports Nutrition and Medicine and Science in Sports and Exercise, and has published over one hundred and fifty peer-reviewed research and review articles.
Dr. Ivy has published two books on sports nutrition, Nutrient Timing and The Performance Zone, which uses the latest research to provide nutritional guidelines for the athlete.
The Science Behind PureSport and Nutrient Timing™
Human Performance Labs (HPL) develops superior nutritional performance sports drinks with protein for athletes of all types, from world class professionals to club sport amateurs and weekend warriors.
Created by Dr. John Ivy, renowned Chairman of Health and Kinesiology at the University of Texas at Austin, PureSport Workout and PureSport Recovery formulas (patent pending) nutritionally enhance the human body’s performance during and after strenuous athletic activity.
What's in PureSport Nutritional Performance Sports Drinks?
- Whey Protein Isolate is rich in essential amino acids and provides quick muscle recovery
- Maltodextrin is a complex carbohydrate for long-lasting, sustained energy
- Sodium replenishes losses due to perspiration
- Magnesium aids in protein synthesis that helps prevent muscle breakdown
- Potassium helps keeps body fluids in balance
- Gluten-Free and Caffeine-Free
PureSport Workout - How it works
The combination of dextrose and fructose is important because you get a faster rate of carbohydrate uptake into the circulation from the intestines, and possibly a faster rate of muscle carbohydrate uptake. The intestines have several different sugar transporters. There is one for glucose and one for fructose. If you saturate the glucose transporter, providing more glucose will not increase the rate of absorption. However, by providing a different sugar (fructose) you can increase the rate of absorption.
The carbohydrate to protein ratio is 2.67 to 1. This provides enough protein to facilitate glucose uptake in muscle without inhibition gastric emptying (movement of drink from the stomach to the intestines). It may also help with maintaining plasma volume during exercise in the heat. When we exercise heat is a by-product of metabolism and this is mainly dissipated by sweating (evaporation). Body water loss causes plasma volume to decline, which can adversely affect performance. It is important to maintain plasma volume. The ingestion of protein along with certain electrolytes such as sodium will help retain plasma volume.
PureSport Recovery - How it works
The combination of carbohydrates will accelerate glucose absorption from the intestines and increase rate of muscle glucose uptake for rapid glycogen storage. The additional protein will help with this process by increasing the blood insulin response. The added protein (18g in a 2.67 to 1 ratio) will increase muscle protein synthesis resulting in reduced muscle damage, increased muscle tissue repair and increased training adaptation.
There are a number of studies now that show the benefit of adding protein to a carbohydrate energy drink and recovery drink. The protein added to a energy drink will increase aerobic endurance and reduce muscle damage caused by hard exercise. The protein added to a recovery drink has been shown to increase muscle protein synthesis, to reduce muscle damage, to accelerate the recovery of muscle glycogen stores, to lower the risk of upper respiratory infection, to enhance the recovery process and increase subsequent exercise performance.
Consuming the workout drink before and during activity will help keep the individual hydrated, maintain energy, and slow down muscle breakdown. Immediately after exercise or as soon as possible consume the recovery drink, to help replenish muscle glycogen stores, slow down cortisol release, and to rebuild muscles.
PureSport complies with and exceeds the specifications and guidelines of all worldwide sports governing bodies. PureSport is manufactured at National Science Foundation certified and Dallas, TX-based Custom Nutrition Labs.
